More and more women in the music business say they have had enough.

A draft of a letter circulating among high-ranking women in the music industry calls for major changes at the Recording Academy, which presents the Grammys, including publishing the demographics of its voting members and creating a plan to include more women, people of color and members of the LGBTQ community.

"We need a leader to think outside of the metaphorical box and start demanding all voices be heard," reads the draft, a copy of which was sent to NBC News.

Twenty-one women have signed the letter. The letter adds that if the group’s demands cannot be met, Neil Portnow, the academy’s president, should step down.
